T T oggle lever for brake lock (digging brake)
The digging brake is made up of the service brake and a locking
mechanism on the service brake pedal consisting of a toggle lever
(A) and a lock pin (B).
Apply the digging brake by depressing the service brake pedal,
without depressing the toggle lever, so that the toggle lever
engages the lock pin.
Release the digging brake by pressing down the toggle lever.

If the machine is equipped with electric digging brake, the service
brake pedal will lock electro-hydraulically in W- or C-mode when
the machine is standing still.
The toggle lever must be locked in a parallel position to the service
brake for the electric digging brake to function, otherwise the
digging brake will work mechanically, see above.
To lock the toggle lever in a parallel position to the service brake
press down the upper end of the toggle lever without depressing
the service brake and to release press down the lower end.
Use the switch on the right instrument panel to select and apply
the electric digging brake.
Upper end of switch pressed down = electric digging brake is
selected or deactivated.
Releasing the red locking device (1) by pressing it down and
pressing down the upper end of the electrical digging brake
switch (2) simultaneously = electric digging brake is applied,
provided that W- or C-mode is selected, the toggle lever is
locked parallel to the service brake and the machine is standing
still.
The electric digging brake is released when the engine is running,
T-, W- or C-mode is selected, the control lockout lever is in upper
position, travel direction is selected and the travel pedal is
pressed.
In this case the pivot axle locking is unlocked too.
In case of manually locked pivot axle locking the axles stay
locked.
